T o all whom 'it may concern.: v

J. SHIRK and SOLOMONV COHEN, citizens of. the United States, and residents of the city`ofl New York, in" the county of New York and State of New York, have invented certain new and useful Electric Press Irons, of which rthe following is a specification. V

This invention relates to electric Press irons and is directed to an automatic switch and stand therefor adapted to facilitate the use of such irons,l increase the efficiency thereof and effect economy of power and material and longer life of the iron and its parts and attachments.

More particularly the invention relates to a stand and automatic switch for' electric irons whereby the .circuit is closed and the iron-heated when the same is in place on the stand and theU circuit broken ywhen the `iron is removedl from' the stand by the operator. 4 y c One object of our invention is to provide in an iron and stand of the characterv described an automatic switch of simple construction and positive, quick and efficient in I its operation. f

Another object of ourinvention is to proL vide a stand and automatic switch for electric press `.irons for the purpose described and which shall be adapted for use with any stand electric heating irons without necessitating more than very simple and easily made modifications or.. attachments thereto and which shall be further simpleppositive and efficient in operation and cheap andV easy to manufacture.

A further'obect of our invention is; to

provide an `automatic switch for electric to be operated b'vy the weight of the iron to connect the electric supply thereto.

`A stillfurther object ofbur invention is toprovide an automatic switch of the 'iwith the parts shown in' off position; that 'Patenteagnly 4, 1922.-

Fig. 3' is ay detailed cross-section in plan cut along'line 3--3 of. Fig. 2; l

Fig. 4is a partial cross-sectional view cut along line4-4 of Fig. 2;

Fig. 5 is a. partial cross-sectional view in y elevation of a modification showing a simpliiied form` for the switch mechanism and also showing an adaptation of our invention for making a touch Contact with the iron instead of socket Contact; and

Fig. 6 is a partial detailed cross-sectional lview in plan cut along linev 6 6 of Fig. 5.

Referring -in detail to the drawing, the heating (stand. comprises a base portion 10 and the support 11 for the iron or like eleo- 7 trical apparatus 12; rear of the stand'is a casing 13 lined on the inside with insulating material such as 14, 14. The casing is closed at the top and the rear side by insulating material such as the composition material 15, 15. With- Extending from the.

in this casing is mounted the` automatic Vswitch mechanism which will not Vbe described.

A pair of'actuating armsl, 16 are pivotedto the sides of the casing as at lifI 17 and areprovided at the free ends with a projection or ear 18.18. The free ends .ears 18, 18.-@ are adapted to normally pron ject above the bottom of the support 1-1 as press irons and the like apparatus adapted through an opening therein--as-shown in F `ig. 1 when thgJ iron is not ini osition on the stand. Pivoted to each o the arms 16, 16 asat 19, 19 is a link member 20, 20l

and pivoted to each ofthe latter as' at 21, 21 is an insulated arm 22, 22 and a contact arm 23,23 having lone end thereof shaped as at 23a so as -to form a plug adapted to enter into the Contact sockets 24, 24

and projections .ofthe arms 16,16 and the which connect with the heating coil of theiron or other electric .apparatus not shown). The other ends of these contact arms are I bent away as at 23b So .as to be disposed in operative relation lto the 4contact clips 29 hereinafterr referred to. The arms 22,- 22 v are further pivoted on a shat25 journaled in bearing member 26 suitably secured to the side of the casing as at 27.` Secured within the casing as at the top, by means of screws or the like fastening means 28 are the contact clips 29, 29 in operative relation to the bent ends 23b of the contact arms. .The contact clips29, 29 are connected to the electric supply by means such as binding posts and lead wires 30 as will be readily understood'.

The operation of our heating stand and automatic switch will now be understood. The actuating arms 16, 16 are normally. in the inclined position shown in Fig. 1 with the free ends thereof projecting above the support 11 by reason of the overweight of the parts of the switch mechanism to the right of the fulcrums 17 and 17 respectively, as will be readily understood. When theiron or the like apparatus is placed in position on the'sta-nd as in Fig. 2, the weight of the iron acting downward on the ears 18, 18 of the arms 16, 16) force the arms to move forward about the pivots 20, 20 -until they reach a substantially horizontal position as shown in this figure. The links 19, 19" movef upward andbecome substantially vertical, at the same time causing the link members .22, 22 and ther contact arms 23, 23 to rotate about their pivot 21 into substantially horizontal position when the ends 23` enterthe sockets 24 on the rear of the iron and the ends 23'J make contact with the clips 29, 29 as shown in Figs. 2,

y 3 and'li, thus connecting the heating coil to 4modified form' shown a touch ends of the arms 23, 23d .being bent to prot l the electric supply throughV said contact arms 23, '23 as will be readily understood.

In the modified form illustrated in Figs. 5

and 6, we have shown a simplified construction operating on` the same principle in which, however, thecontact arms 23C, 23d (havingthe same functin as members 23, -23 hereinabove described) are pivoted on one rsliaft preferably of insulating material adapted to be operated by a single arm 16' similar in construction and functioning in the same manner .as the arms 16, 16 hereinabove referred to. Pivoted to ths arm 16l isa single link member 20 which is pivoted at its up er end centrallyon the'shaft 31l as at 33. n this modified form the contact arms 23, 23 "are provided with elongated slots34 at the forward contacting ends thereof adapted to slide over the pins 35, 35 suitabl secured in the A"sides of the casing. nstead'of a socket contact we have in this vide contacting pieces 36, 36 adapted to make touch contact fwith the contact studs v37, 37 on the rear of the iron. To maintain the switch mechanism in position` when theiron is on the stand as shown in full lines in Fig. 5, we provide a sp'rilig member ytric sad irons and the li contact, the

` on the stand.

The operation of our modified yform is similar to that of the form-shown in Figs. l, 2, 3 and 4. The counter-poise is first adjusted to correspond to the'weight of the iron to be used. As the iron is placed on the stand it pushes downward on thearm 16 which in turn pushes upward on the link 20, thus causing the contact members 23C, 23d to rotate about' the shaft 31 from the dotted position shown. in Fig. 5 into the position shown in full lines, thel slots 34 moving over the ins 35, 35 until they lodge in the ends of t e slot. The rear ends v23e of the contact arms 23", 23 snap into the clip 29, 29 while the contact pieces 36 36 move into touch contact with the studs 37, 37 thus yconducting the currentffrom the clips to the irons.

. While wey have explained and described our invention in connection with the use thereof with electric irdns, it will, of course, be understood that my improved heating stand and switch mechanism may be used with any electric tool or apparatus having 100 suitable contacts and designed to be electrically heated Aor otherwise connected to a source o1".l electric supply.

Having thus described my invention, I claim as new and desire to ,secure by Let- 105 l ters Patent contact making arm, means for transmittingmotion from said actuatin member to said contact making arm where y the latter connects the electric circuit to the iron, and means'for normally maintaining said actu- `ating arm above the support in position to be operated by the iron.
